MACHINE FOR MAKING CHAPLET Application led March 12, 1928.

My invention yrelates to a machine for making chaplets, and l declare the following to be a t'ull, clear, concise and eXact description thereof -snflicient to enable anyone skilled in the art to .which it appertains to malte ,and .use the same, reference being; had to the accompanyingg` drawings in which like reference characters refer to like parts throughout the specifications. i The object ot the invention is to provide a machine .that will make chaplets, out of .a strand. oit wire, for use in holding' the cores yused 'in casting moulds in foundries. To this end the machine is equipped to feed the wire intermittently towards the cutting and severing knives from wl'ience it is carried `by an intern'rittent rotary disk to the winding; land grooving mechanism and from thence to the flattening and discharging parte. The several operations oit severing, winding growing, ilatteningand dischargin movements in making' the chaplets are .@"f'nchronized to f such an extent that ,the iiiachine can turn them out very rapidly.

The obj ect will be understood by referring 'to the (lrawings, in which:

Referring more particularly to the ydrawings, the machine embodies a table 1 ymounted by legs 2. A. master yshatt 3 is supported above `table `1 by a 4bearing 5 mounted on an auxiliary support 6 `at one end and in bearing'y 7 mounted on table 1 at the other, Shaft 3 is revolved by pulley wheel 10 which is adapted ,to turn thereon. Cam is carried on shaft 3 and is adapted to Lturn therewith. It is in en- 1sagement with roller 16 to .turn on shaft 17 having` bearings in rock member 20 that comprises two ,bars y21, 21 .held apart by bolts and spacing sleeves 22. One end vof each of bars 21 is jl'ulcrumed upon a shaft 23 projecting laterally from "table 1. The opposite ends of hars E21 are United byiblock 25 which has a central socket for the receptiontherein of a halt-ballen the end of adjustable shaft 2G. The upper end of shaft 26 forms a universal joint connection with the lower part 27 of rock member 30 which is pivoted to turn on shaft 31 mounted in bearings'in brackets 32, ,32 supported on and extends laterally from rock shaft'et.'

Rook shaft is carried in bearing brackets f 32, 32 mounted on table` 1. Rock shaft 45 has formed integral therewith an upstanding socket 47 provided with an aperture for mounting adjustable rod t8 held in place by set screw 116. rlhe upper end of rod 48 projects upward through an aperture made in clamping blocks L19, L19 that are held t0- gether by bolts 50, 50. rlfhe forward ends of block a9, L19 are recessed for the adjacent end of link 52 that is pivoted on one of the shafts at one end and on shaft 55 carried by reciprocating feed member 56 at the other. Feed member 56 is recessed at 57 for this purpose. ri"he turning of master shaft 3 will rock, therefore, shaft Ll5 and through link member 52k reciprocate feed member 56 between adjustable stop blocks 57 and 58, which can be set at any predetermined position along rod 60 to limit the extent of reciprocation of feed memberl 56.

Feedmember 56 is mounted to slide on rod 60 which is carried in a bearing formed in bracket 61 bolted at 62, 62 to frame 63 and in adjustable block 58 which is bolted at 65, 65 to frame 63. Elongated slots 66, 66 are made in block 58 for the projection of bolts 65, whereby to allow for the horizontal adjustment of said block 58.

F eed member 56 is equipped with a central recess 70 having its upper surface ta` pered towards one end for the reception of a movable clutch block 71 which is adapted to slide back and forth in recess 70 for the purpose of clutching and releasing wire 35 at the proper intervals. ln order to reduce the friction, whereby to aid in the slid ing movement of clutch block 71 anti-friction rollers 72 are carried in open bearings 77 formed in the top part thereof. Side plates78 are Vbolted to block 71 to hold rollers 72 in bearings 77. Clutch block 71 is held yieldingly in a position adjacent the narrow endk of recess 70 by a coiled spring 73 disposed between the broader end surface 7d of block 71 and collar 75 fixed to move with adjustable screw bolt 76l mounted in a threaded bearing in the end surface of Yfeed member 56. The turning'of bolt 76 will determine the degree with which clutch member 71 will grip wire 35 for feeding the same forward. Clutch block 71, however, can be forced forward and held temporarily for convenience in disposing the free end of wire 35 thereunder originally by bell crank lever 80 which is fulcrumed at 81 upon a pivot mounted in feed member 56. Lever 80 is actuated by a cam 82 revolvable on a stud or shaft that is threaded to a corresponding recess in member 56. rlhe cuter surface of cam 82'is equipped with a counter-sunk groove for the application of a screw driver, not shown. A lateral projecting stud 83 is mounted on the outer side of clutch block 71 and lies adjacent the depending end of bell crank lever 80.

lVire 35 passes through feed member 56 which is recessed on either side beyond the larger central recess 70 for the purpose of a guide and under clutch block 71. The undersurface of block 71 is equipped with a semi-cylindrical groove 79 for the partial reception of wire 35. rEhe other half of said groove is formed in the contiguous surface of feed member 56.

`When feed member 56 moves forward to push wire 35 towards the operating parts feed member 56 towards the operating parts of the machine. Likewise, on the reverse movement of feed member 56, clutch block 71 will move automatically towards the larger end of recess 7 0 against the pressure of spring 73, whereby to release wire 35 and, thereby, permit feed member 56 to move rearwardly to secure a new grip on wire 35.

Moreover,-wire 35 is held stationary during this rearward movementy of feed member 56 by elevation 90 formed integral with rock bracket 91. To this end 'bracket 91 is fulcrumed, upon a shaft 92 that has a bearing in block 58a. The outer end of bracket 91 is bifurcated for the reception of the upper end of adjustable Llink 95 which is pivoted to bracket 91 by shaft 96. Shaft 96 is held in place by Cotter pins 97, 97. The lower end of link 95 is pivoted to shaft 98 carried in bearings in arms 100, 100 that are held in spaced relation. Arms 100 are pivoted at their rear ends to studs projecting laterally from frame support 101. The outer ory free ends of arms 100, 100 carry a roller 102 that turns loosely upon its bearings and is in engagement with a cam roller 103. Roller 102 is held yieldingly against the surface of cam roller 103 by a coiled spring 105 that is attached at one end `to a cross rod carried in arms 100 and at the other to a peg 106 mountedin frame support 101. Gam roller 103 is adapted to allow adjustable link 95 to move upward under tension of spring 105 and thereby rock bracket 91 upward sufficiently, whereby elevation 90 of rock bracket 91 will pinch and hold wire 35 between its own surface and the upper surface of the aperture made in block 58 irmmso through ywhich said wirepasses during such interval as determined :by `the time it takes `the severed part into a chaplet.

J ust before being severed the free end of wire 60 will Ihave been pushed through eonical shaped guide aperture in block 111 that is made integral with bracket 112, which is bolted to frame 63, vand :through one of the apertures 115 made in intermittent rotary disk 116, as said aperture is brought into alignment. `l7Vire 35 will be projected therethrough and beyond until its further motion is arrested by adjustable stop bolt that is screw mounted to bracket 121 which is attached to upstanding frame support 122.

Guide block 111 is made in two parts7 the lower half 123 of which is hingedr to part 124 at 125. It is held normally in full line position shown in Figs. 1 and 3 by a` coiled spring 126 that presses against the lower surface of part 123 and is held in place by an adjustable bolt 127 mounted to bracket 128 that is in turn attached to bracket 112. Part 123 is hinged to part 124 and will yield sufficiently against the pressure of spring 126, whereby the cut piece of Wire 35 can escape from conical guide aperture 110 in a horizontal position, as it is carried around by disk 116.

Aperture 115 in disk 116 is made through a circular` die 130 that is set in a counter recess in disk 116 and rigidly fixed thereto. A countersunk groove 131 is made in die 130, which groove 131 terminates at one end in said aperture 115. Groove 131 is designed to form the lower straight portion 132 of chaplet 133 and to give the initial turn at 134 thereto.

Disk 116 is mounted to turn with shaft 135 in an intermittent manner by means of chain belt that has on its under surface teeth 141 adapted to engage cooperating grooves made in pulley 142 attached to Lturn with shaft 135 and pulley 143 mounted to turn loosely on master shaft 3. Belt 140 passes over a pulley 145 having cooperating grooves and mountedto turn freely on shaft 146 projecting laterally from bracket 147. Pulley 145 is adapted to be adjusted to take up any slack in chainbelt 140.

A disk plate 150 is made integral with pulley 143 which bears against a wooden disk 151 mounted to turn with master shaft 3. A coiled spring 152 disposed about shaft 3 is held between pulley 143 Land an adjustable lock washer 153. Washer 153 is `mount- 4severed wire to the left of disk 116 embed ed on shaft 3 and lis held in predetermined position by set nut 155. Spring 152 will force the .fdisk part`150 of pulley 143 normally against woodenvdisk 1517 whereby to cause said pulley 143 to turn vwith master shaft `3. However, disk `plate 150 will slip past wooden disk 151, whereby pulley 143 will stop rotating with respect to master shaft 3 at predetermined intervals, 'which will correspond to those of disk 116.

The means for holding rotary disk 116 during the proper 'interval embodies a lever formed integralwith flat spring fixed f at 17 to the underside of arm 160. Notches 166 are made in die piecesv 167 that are dovetailed into the periphery of disk `116. Each of the dies is slightly beveled adjacent the notch 166, whereby tto allow spring `pressed tooth to slide in moreieasily. The other or lower portion offlever arm 160 is bifurcated, the parts ybeing held in spaced relation by .spacing bolt 163. A roller 169 is mounted to turn freely on a shaft 170 carn `ried in bearings in the lowermost yendsy of vInen'ibcrs 171, 171 `of lleverarm 160. Roller 169 rests upon cam roller 175 that is mounted yto turn with master shaft A coiled spring 176k fastened at one end to across har ycarried in `lever arm 160 and at ythe other to stud 177 mountedfte upstanding frame support 101 yieldingly `holds roller 169 in contact ywith cam roller 17 5. However, cam .roller will periodically elevate roller 169 and rock lever arm 160, thereby to withdraw itooth 165 from a `notch 166 in disk 116, whereby to .permit disk 116 to turn ,through substantially a quarter `of a circle l.when its turning will lbe again arrested by the engagement of .tooth 165 in `the next succeeding notch 166.

Shaft 135 on `which disk 116 is mounted in a Vmanner to turn .therewith is carried iny bearings formed in upstandine brackets .130 and 181 formed integral with frame `63.

The means for bending that part of the a roller 185 .mounted to turn freely on sh 136 projecting from bracket 137 that is mounted to frameif63. the severed part of wire 35 moves upward and in a horizontal position with one end projecting through disk 116, the part to the left of said disk 116 will come in contact with the lower `surface of roller 185 and be bent at right angles, whereby to lay flat against the adjustable surface of disk 116. n

`The means for twisting wire 35 to form and held by set bolt 217.

the base of chaplet 133 contemplates roller 190 adapted to turn with shaft 191 which is carried in journals 192 and 193 formed integral with upper part of frame 63. Roller 190 has formed on its lateral face a central reduced cylinder projection 194 terminating in a conical part 195 adapted to engage wire 35 at the location of an aperture 115 in a die 130 in disk 116, whereby to form an axis about which wire 35 is wound. The means for twist-ing wire 35 about said axis embodies a small roller 196 mounted on a spindle projecting laterally from the face of roller 190 and adjacent the periphery, whereby said roller 196 will have a planetary revolution about central projection 194, and conical part- 195.

The means for actuating conical part 195 towards and from disk 116, whereby to release disk 116 and clear chaplet 133 for the further turning thereof, contemplates the reciproca-tion of shaft 191. This 1s eected by rock arm 200 which is fulcrumed at 201 upon a shaft projecting laterally from upstanding bracket202 formed integral with frame 63. The upper ,part of arm 200 is bifurcated at 203 to allow for the projection of shaft 191 therethrough. Washers 205 and Cotter pin 206 are used to hold shaft 191 in position with relation to arm 200, The lower depending end of arm 200 rests in contact with an adjustable rod 210 held in socket 211 by set screw 212. Socket 211 isformed integral with rock shaft 213 carried in bearings made in bracket 32 and in frame 63. The means for rocking shaft 213 embodies roller 215 mounted on headed shaft 216 carried in a socket made integral with shaft 213 Contact with cam roller 220 mounted to turn with master shaft 3. A coiled spring 221 connecting the upper end of arm 200 and a bracket 222 formed integral with frame 63 tends to retract shaft 191 and to hold roller 215 normally against the surface of cam roller 220. A chain belt 225 having inwardly extending teeth 226 connects like pulleys 227 and 223 mounted to turn with shafts 191 and 3 respectively, whereby to rotate said shaft 191 from the master shaft 3 in order to turn roller 190. The mechanism for forming grooves 230, 230'in the stems 231 of'chaplet 133 has knives 232, 232 that are removably mounted in holders 233, 233 by detachable pins 234, lwhich fit. somewhat tightly within their respective apertures in holders 233, 233. Knives 232, 232 are in each instance provided with two cutting surfaces 235, 235 by making a vf-shaped recess 236 in between. The vtwo cutting surfaces 235 are spaced apart toy form the grooves 230, 230 in spaced relation to each other, on the stem 231 of chaplet. f

Each of the holders 233 is disposed in an Roller 215 lies inVv open recess 237, 237 in head member 240, and is pivoted thereto at 241, 241. Head member 240 is made integral with shaft 247. The cutting surfaces 235 of knives 232 are held normally away from wire 35 which projects therebetween by a coiled spring 242 that connects in each instance one of the ends of holders 233, 233 and thereby tends to draw said connected ends together and cutting surfaces 235 of knives 232 apart.

Cutting surfaces235, 235 of knives 232 are forced toward each other, whereby to engage the stem 231 of chaplet 133 and form grooves 230 therein by movable wedge 245. l/Vedge 245 is conical in shape and is made integral with disk 246 which is mounted to slide on shaft 247 carried in journals 248 and 249 made integral with frame 250. Moreover, said wedge 245 is adapted to slide longitudinally with respect to shaft 247 for a purpose to be hereinafter described. Belt 251 connects shaft 247 with a Vpulley wheel- 252 mounted to turn with master shaft 3, whereby to rot-ate said shaft 247.

and 260, whereby knives 232 will move forward in parallel relation into proper location to be at the end of the stroke forced towards each other into grooving position, embodies yoke 255 which is concaved to conform to the curvature of disk 246 and carrying antifriction rollers 256 which are disposed on plate 255 in Asuch Vmanner as to be located on opposite sides o-f disk 246. This arrangement of rollers 256 will cause disk 246 to move in a horizontal plane with yoke 255. Yoke 255 is bolted to shaft 260 which is spliced at its end for the purpose. Shaft 260 has loose bearings in journals 248 and 249. A rubber washer 261 is mounted on shaft 260 to act as a cushion stop when shaft 260 is drawn to the right to retract knives `232 from cutting position to clear shank 231 of chaplet 133. A coiled spring 262 is mounted on shaft 260 between journal 249 and adjustable end washer 263, whereby to force said shaft 260 normally towards the right. The contact of conical wedge 245 with rollers 253, one of which is carried in each of the knifev holders 233, will carry said holders 233 and shaft 247 forward or to the left in Fig. 1 in parallel relation to each other until they reach the end of said forward movement. At this instant, collar 264 will make contact with the contiguous ledge of bearing 249 and arrest the further forward longitudinal movement of shaft 247. Conical wedge 245, however, will continue to move'forward and in this instance sliding on said shaft '24", whereby to force the contiguous ends of knife holders 233 outward and knives 233 inward. Said knives 233 will engage thereupon the contiguous surface of wire 35, whereby to form annular groo-ves230 in stem 231 of the chap- The means for reciprocating shafts 247 d let. Furthermore, shaft 260 and the aforesaid parts are reciprocated by upstanding arm 270. The upper part of arm 270 carries an adjustable bolt 271I that abuts against the end of washer 263. rlhe lowerI endiof arm 2i() isheld in socket 272' by set screw 27 3. Socket 272 is formedv integral with' rock shaft 27dwhich has its ends reduced to fornibearings that are carried in bracket 275 at one cnil and wall 25.() of the frame at the other. Spring` 266 will perform also the function of retracting shaft 260 to original position: and to hold roller 279 in Contact with cam 280. f i

Rock shaft 274 has a socket 277 for holding a shaft 27 8 upon which rotates a meinber 279' that is in contact with cam wheel 280 fined to turn with master shaft 3. The turning of master shaft will rotate. therefore arm 274 and through the aforesaid parts above mentioned7 cause arm 27() to press shaft 260 and move said shaft 260 against the tension of coiled spring 262 to the left to force knives 232 into cutting position with the stem 231 of chaplet 133 T he mea-ns for liattening'thebase part 282 of chaplet 133 provides a trip hammer 285 that is fastened to one end of a horizontally reciprocating shaft 286 carried in a bearing 87 made as part of frame 63. A flatlaminated spring 290 boltedy at its lower end to angular bracket 291 forces hammer 285 against the base part 282 of chaplet 133 whereby toy flatten it. The face of hammer `285 is counter-sunk at 233a to provide an annular ridge 285. Ridge 285b will encompassand thereby prevent the base 282 of chaplet 133 from spreading. The upper end of spring 296 projects upward through yoke 292 that is held to diskf293 by the projecting trunnions 294, 294i made integral with en larged portion 295 of disk 293. Disk 293 is made integral with shaft 286. Bracket 291 is bolted to table 1. Rock yoke 30 fulcrumed to turn on shaft 31 carried in bearings formed in brackets 32 and 32 is adapted to return hammer 285 to its original position against the pressure of flat laminated spring 290. To this end the upper part of rock yoke 30 provides space for the projection ytherebei-wecn of shaft 286 andhas upper ends with curved surfaces that make contact with the adjacent surface of disk 233. A coiled spring 305 connected at one end to rock yoke 36 and. at the other to supporting part 306 of frame 63 tends to rock yoke 30 towards the left, whereby to trip the releasing pawl.

or trigger 310. F or this purpose9 rock yoke 3() has mounted thereto a transverse bar 3.11 adapted to make contact with the under beveled surface 312 of trigger 310 when said yoke 30 is rocked towards the left or counter clockwise. n

Trigger 310 is fulcrumed at 315 to overbangiug wall 316' ref frame suj'ijsrtifng member 317 which is recessed at 318 for theproj ection. of trigger 310. A shoulder is formed at 320 ontr'igger310, whereby to engage the cooperating shoulder made integral with han'imer 285. The engagen'ient of shoulder 32() of trigger 310 with the cooperating shoulder of hammer 285 will hold said hammer against the tension ofliat laminated spring 290 andy in locked position from which it can be released by the engagement of transverse bar 311 with the opposite beveled under surface 312 of trigger 310. A coiled spri 319 fastened at one end to trigger 31() .ad at the other to bearing part of the frame tends to hold trigger 310 in engaging position with hammer The forward part of ytrigger 310 is beveled at 322 to allow part of a hammer 285 to ride therepast into engaging positon with trigger 310. y

in arm 325 is pivoted to the greoved part of bracket 326 and is adapted tos be swung with its fore end against disk 293, whereby to lock hammer 285 in locked position temporarily, while feeding wire manually to the machine. Shaft 327 on which arm 325 is fixed as a pivot is extended and bent at right angles, whereby to act as a handle 328 to move said arm 325 towards and from lockposition.

rlfhe means for actuating rock yoke 30 embodies a connecting shaft 26 that has a ball Les and socket joint connection at 331 with yoke n part of pin is housed in a movable sleeve 338k carried in guide member 336 that lfasteiied to cylindrical bearing part 337 of the frame. 'llhe opposite end of pin 335 is enlarged in diameter. An adjustable washer 340 is mounted thereon. rlhe end surface of washer 340 abuts against the latter inner end surface of rock member 3111 which projects through an open recess made in bracket 342 that is bolted at 343 to the flattened milled surface of cylinder 337. A shaft 345 passing through bracket 3.42 forms a pivot upon which rock member 3&1 is fulcrumed. Cotter pins 3&6, 3416, are used to hold shaft 345 in place. Said inner end of rock member 3111 projects also into recess 347 formed in cylindrical part 337 tomake the aforesaid contact with washer 34.0 wh'ch occupies a position in said recess 347.

A coiled spring 339a surrounds sleeve 338 between head 33380' and one of the end walls 338b of recess 347 in reduced part 337 and tends/ifo .ib said sleeve towards 'the left or 'e the cable 360 in place.

away from disk 116. Likewise, a coiled.

spring 339 of heavier and stiffer degree sur-v rounds the enlarged part of pin 335 between washer 34() and head 338a of sleeve 338, whereby to hold said pin 335 and sleeve 338 in given predetermined relation. wWhen member 341 is rocked inV given direction it will push both pin 335 and sleeve 338 together. In this action of pin 335 and sleeve 338, the end of'sleeve 338 will push against the contiguous end of shank 231 of chaplet 133 and force it as far as the adjacent later 'surface of disk 116, whereupon the heavier spring 339 will yield sufficiently to allow pin 335 to move further forward through aperture 115 in die 130 mounted in disk 116 to eject shank 231 of chaplet 133 therefrom.

The outer end of rock member 341 is connected to rock arm 350 by connecting link 351 held in a recess made in the bifurcated outer ends of rock member 341 and of rock arm 350 by pivots 352, 352. Pivots 352, are held in place by cotter pins 353, 353.

`Rock arm 350 is adapted to turn with rock connecting shaft 355 which project-s upward through the recess 356 in one of the ends of bracket 342. The lower end of connecting shaft 355 is iixed to turn with rock arm 357 and has a lower bearing in bracket 358 bolted to the side of frame support 359. rllhe outer or free end of rock arm 357 is connected by a cable wire 360 to adjustable bolt 361 that has a. loose bearing in upstanding rock arm 362. Clamps 363, 363 are employed to hold A Rock arm 362 is pivoted at 365 to bearing bracket 7. A roller 370 is mounted to turn on a stud projecting laterally from near the lower end of rock arm 362. Roller 370 is in Contact with the surface of a cam roller 371 fixed to turn with master shaft 3. Cam roller 371 has formed on its periphery a flange 372 forming an abrupt shoulder, whereby to give a quick jerk on cable 360. This in turn will through the connecting parts above described, etlect a quick motion of chaplet discharging sleeve 338 and pin 335. A coiled spring 37 5 is disposed about the shank of bolt 361 and bears at one end against the adjacent surface of rock arm 362 and at the other aga-inst lock nuts 376, 376. Adjusting the tension'of spring 375 by turning lock nuts 37 6 will determine the degree of presure of roller 370 against cam roller 371.

Well known wire straightening members 380 and 381 employing adjustable rollers 382 are are attached to frame 63, whereby to straighten wire 35 before it enters the machine.' Furthermore an arm 390 bolted to frame 63 carries on its outer end two depending felt pads 391, 391, that are kept saturated with oil, whereby to lubricate the wire 35 as it enters wire straightening members 380 and 381.

' The operation of the machine is effected by first manually feeding the end of a strand of wire 35 through felt pads 391, 391, wire straightening members 380 and 381, through the aperture in feed member 56, through the aperture in adjustable stop block 58, over cutting edge of elevation 90, into conical guide aperture 110 in block 111. During this manipulation of wire 35 master pulley V can be turned by hand to move the operating parts slowly to effect the feed. Arm 325 will be moved to full line position illustrated in Figs. 1 and 2, whereby to prevent trip hammer 285 from moving forward. Also clutch block 71 will be forced towards the larger end of recess 7 0 by rocking` bell crank lever 8O by means of cam 82, whereby to relieve the tension of clutch block 71 on wire as it is being pushed through the aperture in feed member 56.

immediately wire 35has been thus disposed arm 325 will be moved to dotted line and lever 80 to full line position illustrated in Fig. 1. -The power will be turned on to rotate master pulley 10 and hence master shaft 3. -As member 56 moves forward to feed wire 35 through an aperture 115 in intermittingly rot-ary disk 116, clutch block 71 will automatically move towards the rear or narrower part of recess 70, whereby to grip wire 35 temporarily, while feed member 56 thus moves forward towards block 58. During this feeding motion of member 56 the free end of wire 35 Will be pushed through an aperture 115 in disk 116 and therepast until it reaches stop bolt120. Immediately wire 35 has reached this position bracket 91 will rock upward, whereby to cause elevation thereon to pinch wire 35, whereby to hold it until feed member 56 has returned to the left in its original position against stop 57. Immediately feed member 56 has reached this latter position elevation 90 will rise still further under influence of cam 103 and connected parts to cut and sever wire 35 at the proper predetermined distance from its free end to form a chaplet. Member 56 is now ready to feed wire 35 again forward.

In the meantime, cam roller 175 will have rocked lever arm 160, whereby spring pressed tooth 165 will be released from one of the four notches 166 to permit disk 116 to rotate through a quarter turn to bring the severed piece of wire 35 opposite the winding and groove cutting mechanism. As said severed piece of wire moves upward in horizontal position it will force itself out of the spring yielding cover 123 of guide block 111. Cover 123 will snap back into place by force of spring 126. The severed piece of wire will be bent at right angles by roller 185, whereby to lie parallel to the lateral surface of disk 116. On reaching the winding mechanism disk 116 will be held again sta'- tionary by tooth 165 of arm 160 snapping into said succeeding notch 166. At this instance roller 190 will advance under the iiifluence of cam roller 220` and connecting parts to* project conical part 1195 of roller 190 into' the adjacent aperture 115m die 130 to formy an axle about which wire 35 will be turned by the planetary revolution of small roller 193 mounted adjacent the peripheral edge ofthe later face ofroll'ei` 190 about conical part 195- as an airis.

Simultaneously with thisv twisting operation, knives 232 will be forced into conftact with stem` 231 of( chaplet 133I by the rocking of arm 274 under influence of cam roller 371 against spriiigpressed shaft 260, which carries yoke 255` therewith. Yoke 255 being pressed forward in engagement with disk 213 will canse knives 233 to move in parallel: planes therewith and when adj ustable collar 2311- comes into contact with journal 2417 to cause conical wedge 245 to continiie its forward movement, whereby to force inward knives 232, 232 into engagement with stem 231 of chaplet 133. Knives 232, 232 will be revolved simultaneously in a planetary manner about wire 35 by niastei' shaft 3 connected to shaft 2117 by belt 251 to e'ect annular grooves 230. 230. Like vise roller 190 will be revolved by the chain belt connection of shaft 191 with master shaft 3.

immediately the winding and groove cutting operations have been completed, shafts 191 and 230 will recede the one under influence of coiled spring 221 and the other un der spring 260, cam rollers 220 and 370 cooperating in this movement. At this instant disk 116' will be permitted to again rotate through another quarter turn to bring the chaplet thus far formed opposite hammer 285 and the ejecting mechanism. Hammer 285 will ge tripped by the moving forward of rock yoke 307 whereby its cross bai' 311 will engage with the under beveled surface 312 of trigger 310 and thereby tilt trigger 310 to release shoulder 32() thereof from engage ment with the cooperating shoulder on hammer 285. Hammer 285 will fly forward immediately under the influence of laminated spring 290 to hit the coiled base part of chaplet 133 su'fiiciently hard to Hatten the opposite surfaces of the wire 35 forming such base portion.

Thereafter hammer 285 will be retracted to cocked position by the reverse rocking of yoke 30. its upper ends in this instance bearing against disk 293. Yoke 30 will be actuated synchronously by its connection with master shaft 3 through connecting shaft 330, rock member 2O carrying roller 16 which is in contact with cam roller 15 mounted to turn with said master shaft 3.

immediately hammer 285 has been retracted the ejecting mechanism comprising sleeve 338 and pin 335 will move forward under influence of their indirect connection with cam roller 371 on master shaft 3,

Therea' dowiifchi-ite into a suitable container `not shown.` Springsl 339 will retract pin 335 from aperture 115 in disk 11.6,and spring 3391" will retract sleeve 338. Bockk member 3&1 will cooperate in this retraction of pin 335l and sleeve 338 under influence of coiled' spring 400 that is attached at one end to link and' at the other to bracket 342, such manner as to exert a pull towards the right on link 351.

Spring 401 connecting socket 47 of rock shaft 5i with frame support 317 is adapted to aid in turning shaft 45' tothe right whereby to quicken the feeding stroke of' meinber 5e..
